UG: FESA Bags (Fully Enclosed Single Attachment Bags )

Availability: ,

Unique Group’s Seaflex® product line offers FESA Bags. It is an enclosed type of ALB that has a capacity of up to 35t. We have designed, developed and manufactured a Fully Enclosed Single Attachment (FESA) variable buoyancy system, for operations which involve elements of both lifting and towing or where there’s a requirement to drop and catch a structure midwater.

Features

Utilises multiple PRVs each capable of venting air at more than 2 cubic metres per minute.

Permits a whole new level of controllability in the critical splash zone.

Handles problems of suction and potential runaway buoyancy brilliantly.

Available in a standard range up to 35t.

Constructed from High Tensile Trevira® Polyester base cloth (either 2 /2 or 3 /3 fibre panama pattern weave) coated with heavy duty UV stabilised PVC coating or, for special applications, polyurethane.

ISO 9001-2009 Quality Management Standard as audited by Lloyd’s Register Quality Assurance along with ISO 14001 and ISO 18001 certificates
